Den foreliggende opfindelse angår en drikkeventil til pelsdyrbure og af den art, det er angivet i indledningen til krav l,og som er ejendommelig ved det i den kendetegnende del af krav 1 angivne.BACKGROUND OF THE INVENTION The present invention relates to a drinking valve for fur cages and of the kind as set forth in the preamble of claim 1, which is characterized by the characterizing portion of claim 1.

5 Det er et påtrængende miljømæssigt problem, at der i større minkfarme frembringes betydelige gødningsmængder, som bør behandles forsvarligt for netop ikke at give miljøproblemer, og udviklingen går i retning af, at der gøres brug af egentlige gylletanke til opsamling af 10 affaldet. Dette tilføres fra langstrakte aflejringszoner nedenunder de forekommende rækker af minkbure, idet det viser sig, at dyrene altovervejende afleverer gødningen ved den ene ende af burene, nemlig den ende, ved hvilken drikkeventiludrustningen findes. Der er derfor tale om 15 en veldefineret og forholdsvis smal aflejringszone under hver burrække, hvorved det er en overkommelig opgave at flytte den faste og flydende gødning til gylletanken under anvendelse af mere eller mindre udviklede transportsystemer.5 It is an urgent environmental problem that in large mink farms considerable quantities of fertilizer are produced, which should be treated properly so as not to cause environmental problems, and the development is towards the use of actual slurry tanks to collect the 10 waste. This is supplied from elongated deposition zones beneath the occurring rows of mink cages, as it turns out that the animals predominantly deliver the fertilizer at one end of the cages, namely the end at which the drinking valve equipment is located. Therefore, there is a well-defined and relatively narrow deposition zone under each cage row, which makes it an affordable task to move the solid and liquid fertilizer to the slurry tank using more or less developed transport systems.

20 Det er dog herved en uheldig omstændighed, at af lejringszonerne netop forekommer nedenunder det område, hvor drikkeventilerne er placeret, idet der så i gødningen indblandes nedfaldende overskudsvand, hver gang dyrene betjener ventilerne. Dette vand indgår dermed i 25 gødningsmængden og forårsager, at denne derved øges ganske betragteligt, således at gylletanken skal være måske 3-5 gange større end ellers nødvendigt.20 It is, however, an unfortunate circumstance that, of the camp zones, it is precisely below the area where the drinking valves are located, so that in the fertilizer, falling excess water is mixed every time the animals serve the valves. This water is thus included in the amount of fertilizer and causes it to increase considerably, so that the slurry tank must be maybe 3-5 times larger than otherwise necessary.

Det er almindeligt accepteret, at drikkeventilerne bør give mere vand end strengt nødvendigt for dyrenes 30 drikkekapacitet under brugen af ventilerne; denne kapacitet er ret beskeden, og hvis ventilpassagerne er tilsvarende snævre risikeres det let, at de stopper til ved den næsten uundgåelige tilstedeværelse af småpartikler i det tilførte vand. Por så vidt angår selve vandforbruget 35 er det uden væsentlig betydning, om der foregår en vis overdosering, og denne er i hvert fald retfærdiggjort DK 169273 B1 2 vedf at den i vid udstrækning kan tjene til at hindre blokeringer af ventilerne. Det omtalte problem ved det tilhørende overskudsvand optræder derfor kun i forbindelse med gødningshåndteringen, hvor problemet til gen-5 gæld er særdeles mærkbart. Det hører i øvrigt med i billedet, at en betydelig del af overskudsvandet navnlig i "hvalpetiden" fremkommer ved, at dyrene leger med ventilerne.It is generally accepted that the drinking valves should provide more water than is strictly necessary for the drinking capacity of the animals during the use of the valves; this capacity is quite modest, and if the valve passages are similarly narrow, it is readily risked that they stop at the almost inevitable presence of small particles in the supplied water. As far as the water consumption itself 35 is concerned, it is of no importance whether there is some overdose, and this is at least justified in that it can largely serve to prevent blockages of the valves. Therefore, the mentioned problem with the associated surplus water occurs only in connection with the manure management, where the problem of re-debt is very noticeable. Moreover, it is part of the picture that a significant part of the surplus water, especially during the "puppy period", is due to the animals playing with the valves.

Opfindelsen har til formål at angive en drikkeven-10 til, som dyrene kan betjene uden at der afgives overskudsvand i væsentlig grad, således at gødningsmængden kun i meget begrænset grad forøges med nedfaldende drikkevand. Det er herved en opgave at tilvejebringe en anvendelig ventil, som har begrænset gennemstrømning 15 uden dog at være let tilstoppelig.The invention has for its object to provide a drinking water to which the animals can operate without substantially discharging excess water, so that the amount of fertilizer is increased to a very limited extent with declining drinking water. It is hereby a task to provide a usable valve which has limited flow 15 without being easily clogged.

Opfindelsen bygger på den betragtning, at dyrene betjener ventilerne på to forskellige måder, nemlig enten ved en ret kort skubbe- eller vippebevægelse af den forekommende, udragende ventillegeme, netop til-20 strækkeligt til at åbne ventilen, eller - ikke mindst under leg - ved at trykke ventillegemet helt i bund. Ud fra dette vil det ifølge opfindelsen være muligt at frembringe en ventil, som i både den netop åbnede og den helt "åbne" stilling kun er i stand til at afgive en 25 meget begrænset vandmængde, medens den i en mellemstilling kan give en forholdsvis stor vandmængde gennem samme vandpassage, nemlig således at passagen herved spules ren for eventuelle aflejringer. En sådan spuling vil kun forekomme næsten momentant ved den nævnte bund-30 trykning af ventillegemet, da dyrene normalt ikke vil være i stand til at holde ventillegemet indtrykket kun til den nævnte mellemstilling, og de lejlighedsvise spulinger vil derfor være så kortvarige, at de ikke tegner sig for noget betydende vandforbrug, henholdsvis 35 vandtilskud til gødningen.The invention is based on the fact that the animals operate the valves in two different ways, namely either by a rather short pushing or tilting movement of the projecting projecting valve body, precisely sufficient to open the valve, or - not least during play - by to press the valve body fully to the bottom. From this, it will be possible, according to the invention, to produce a valve which, in both the newly opened and the fully "open" position, is only capable of delivering a very limited amount of water, while in an intermediate position it can produce a relatively large flow of water through the same water passage, so that the passage is thereby flushed clean of any deposits. Such flushing will only occur almost instantaneously at said bottom pressure of the valve body, since the animals will not normally be able to hold the valve body depression only to said intermediate position, and the occasional flushes will be so short-lived that they do not account for some significant water consumption, respectively 35 water subsidies for the fertilizer.

Opfindelsen kan realiseres på flere måder, men det 3 DK 169273 B1 foretrækkes at bruge en ventil af den type, hvor en fjederpåvirket ventiltap strækker sig gennem en ventilpassage og ved dennes indre ende i forbindelse med et tilførselsrør for vandet har et ventilhoved, evt. be-5 stående af en udstående O-ring, som holdes mod et brystområde ved den indre ende af ventilpassagen. Dyrene kan åbne ventilen ved vipning eller let indskubning af den fremstående ventiltap, ligesom de kan trykke tappen helt i bund, indtil den rammer et anslag, eller indtil den 10 forekommende lukkefjeder er helt sammentrykt. Ved en sådan ventil sørges der ifølge opfindelsen for, at ventiltappen generelt er udført med en diameter, som kun er meget lidt mindre end diameteren af ventilpassagen, idet tappen dog har en neddrejning, som er lidt længere end 15 ventilpassagen og som i en mellemposition af tappen er beliggende netop i eller indenfor ventilpassagen. I denne mellemposition, som tappen indtager yderst kortvarigt under indtrykning til og påfølgende tilbagevandring fra fuldt indtrykket stilling, kan vandet få lej-20 lighed til at strømme kraftigere mellem de modstående ender af ventilpassagen, gennem neddrejningen, hvorved eventuelle urenheder kan udspules. Skulle det ske, at der observeres en blokeret ventil, kan man udefra med en finger rokke med ventiltappen og holde denne i lidt 25 længere tid i gennemspulingspositionen.The invention can be realized in several ways, but it is preferred to use a valve of the type in which a spring-actuated valve pin extends through a valve passage and at its inner end in connection with a supply pipe for the water has a valve head. consisting of an protruding O-ring held against a chest region at the inner end of the valve passage. The animals can open the valve by tilting or slightly pushing the prominent valve pin, as well as pressing the pin fully down until it hits a stop or until the occurring closing spring is fully compressed. In such a valve, according to the invention, the valve pin is generally designed with a diameter which is only very slightly smaller than the diameter of the valve passage, however, the pin has a slope which is slightly longer than the valve passage and which in an intermediate position of the pin is located just inside or within the valve passage. In this intermediate position, which the pin occupies extremely briefly during depression to and subsequent return from the fully depressurized position, the water may cause the fluid to flow more strongly between the opposite ends of the valve passage, through the drainage, whereby any impurities may be flushed out. Should a blocked valve happen to be observed, a finger can be rocked with the valve pin from the outside and held in the flush position for a little longer.

Det skal bemærkes, at man fra WO 84/04655 kender en såkaldt bideventil for større dyr, hvor der er sørget for, at ventilen giver tilstrækkeligt med drikkevand i en mellemstilling af ventillegemet, medens der nærmest 30 lukkes helt, når ventillegemet føres til fuldt aktiveret stilling. Det påregnes, at dyrene herved vil lære sig at drikke i "skvulp", idet den normale strøm af drikkevand vil fremkomme i en mellemfase, hver gang ventillegemet bevæges mellem lukket stilling og slutstillingen. Herved 35 imødegås vandspild, men der forekommer slet ikke den situation, at den operative vandgennemstrømning er 4 DK 169273 B1 "svag", og der er ikke tale om, at der i mellemfasen afleveres endda meget mere vand end svarende til dyrenes drikkekapacitet. Funktionelt er den kendte ventil stærkt afvigende fra nærværende ventil, og det skal derfor 5 understreges, at nærværende ventil er specielt beregnet til små pelsdyr såsom mink.It should be noted that from WO 84/04655 a so-called bite valve for larger animals is known, whereby the valve is provided with sufficient drinking water in an intermediate position of the valve body, while almost 30 are completely closed when the valve body is fully activated. position. It is envisaged that the animals will thereby learn to drink in "swell" as the normal flow of drinking water will appear in an intermediate phase each time the valve body is moved between the closed position and the final position. Thereby 35 water wastage is avoided, but there is no situation at all that the operational water flow is "weak" and there is no question that even more water is delivered in the intermediate phase than the drinking capacity of the animals. Functionally, the known valve is very different from the present valve, and it should therefore be emphasized that this valve is specifically intended for small fur animals such as mink.

På tegningen er illustreret en ventil ifølge opfindelsen, idet fig. 1 er et sidesnitbillede af ventilen vist mon-10 teret i et drikkevandsrør, og fig. 2-5 viser forskellige stillinger af ventilens ventiltap.The drawing illustrates a valve according to the invention, fig. 1 is a side sectional view of the valve shown mounted in a drinking water tube; and FIG. 2-5 shows different positions of the valve valve tap.

I fig. 1 er vist et vandrør af formstof 2, som strækker sig langs en række af minkbure og ud fro hvert 15 bur har mindst én drikkeventil 4 bestående af et ventilhus 6, der bagtil har en konisk gevindskåret stuts 8, som på tæt måde er indskruet i et sidehul i røret 2, og en ventiltap 10, der strækker sig gennem huset 6 og en ventilpassage 12 i stutsen 8. Forrest har ventiltappen 20 10 et trykhoved 14 og bagest et ventilhoved i form af en udstående O-ring 16, som samvirker med et bageste sædeområde 18 på stutsen 8. Fortil er tappen 10 omgivet af en fjeder 20, der trykker tappen 10 fremad til lukket stilling af ventildelene 16,18. Dyrene kan åbne ventilen 25 ved at trykke på trykhovedet 14.In FIG. 1, a water pipe of plastic material 2 is shown which extends along a series of mink cages and out of each 15 cages has at least one drinking valve 4 consisting of a valve housing 6 having a rear conical threaded butt 8 which is tightly screwed into a side hole in the tube 2, and a valve pin 10 extending through the housing 6 and a valve passage 12 in the plug 8. First, the valve pin 20 10 has a pressure head 14 and at the rear a valve head in the form of an protruding O-ring 16 which cooperates with a rear seat region 18 on the butt 8. In addition, the pin 10 is surrounded by a spring 20 which pushes the pin 10 forward to the closed position of the valve members 16, 18. The animals can open valve 25 by pressing the pressure head 14.

Så vidt beskrevet er der tale om en velkendt ventilkonstruktion, og det specielle ved ventilen ifølge opfindelsen er, at den radiale frigang mellem ventiltappen 10 og ventilpassagen 12 er meget lille, f.eks. blot 30 0,1 mm, og at der i tappen 10 er tildannet en neddrej- ning 22 beliggende foran og delvis indragende i ventilpassagen 12.As far as described, this is a well-known valve structure, and the special feature of the valve according to the invention is that the radial clearance between the valve pin 10 and the valve passage 12 is very small, e.g. only 30 0.1 mm and that in the pin 10 a pivot 22 is formed in the front and partly protrudes in the valve passage 12.

Med den nævnte ringe frigang tilstræbes det at tilvejebringe et meget lille gennemstrømningsareal, 35 fortrinsvis blot ca. 0,5 mm2, således at ventilen i både let åbnet og helt åbnet tilstand kun kan afgive vand i 5 DK 169273 B1 et tempo, som nogenlunde svarer til dyrets drikkekapacitet. Det kunne være ønskeligt at arbejde med en snævrere ventilpassage og dermed med en noget større radial frigang, men det er fundet væsentligt at opretholde en 5 rimeligt stor tykkelse af ventiltappen 10 med det formål, at denne normalt af messing bestående tap om vinteren kan virke mærkbart varmeledende mellem opvarmet vand i røret 2 og det indre af ventilhuset 6, således at dette derved kan holdes frostfrit.With the said low clearance, it is sought to provide a very small throughput area, preferably only approx. 0.5 mm2, so that in both the easily opened and fully opened state the valve can only deliver water at a rate which is roughly equal to the drinking capacity of the animal. It may be desirable to work with a narrower valve passage and thus with a somewhat larger radial clearance, but it has been found essential to maintain a reasonably large thickness of the valve pin 10 with the aim that this normally made of brass tap in winter can work noticeably heat conductive between heated water in the pipe 2 and the interior of the valve housing 6 so that it can thereby be kept frost-free.

10 Fig. 2 viser ventilen i lukket tilstand. Det vil forstås, at ventilen kan åbnes til normal udstrømning eller udsivning af vand ved en overordentlig ringe ind-trykningsbevægelse af trykhovedet 14, og i øvrigt kan en tilsvarende åbning opnås ved en tværforskydning af tryk-15 hovedet, hvorved ventiltappen 10 som vist i fig. 3 bringes til at kippe tilstrækkeligt til at o-ringen 16 letter lidt fra en del af sædet 18. Når trykhovedet 14 slippes, sørger fjederen 20 for at rette ventiltappen op til lukket stilling.FIG. 2 shows the valve in the closed state. It will be appreciated that the valve can be opened for normal outflow or leakage of water by an extremely low push-in movement of the pressure head 14, and moreover, a corresponding opening can be obtained by a transverse displacement of the pressure head, whereby the valve pin 10 as shown in FIG. . 3 is caused to tilt sufficiently that the o-ring 16 eases slightly from a portion of the seat 18. When the pressure head 14 is released, the spring 20 provides for the valve pin to close in position.

20 Hvis trykhovedet udsættes for en egentlig indtryk- ningskraft, trykkes ventiltappen 10 forholdsvis let i bund, hvilket svarer til den i fig. 4 viste stilling. Inddrejningen 22 er her skubbet frem til bagendeområdet af passagen 12, således at forenden af passagen igen er 25 vidtgående udfyldt af ventiltappen 10 til fortsat væsentlig begrænsning af udstrømningen.20 If the pressure head is subjected to an actual compressive force, the valve pin 10 is pressed relatively lightly to the bottom, which is similar to the one shown in FIG. 4. The pivot 22 is here pushed forward to the rear end area of the passage 12, so that the forward end of the passage is again extensively filled by the valve pin 10 to continue to substantially reduce the outflow.

I den i fig. 5 viste mellemstilling er inddrej-ningen 22 beliggende netop ud for ventilpassagen 12. Det ses, at længden af passagen, og at der derfor nu kan 30 foregå en væsentligt kraftigere gennemstrømning, hvorved eventuelle aflejrede urenheder kan bortskylles. Denne stilling vil normalt kun indtages ganske kortvarigt under ventiltappens bevægelse frem og tilbage mellem fuldt lukket og fuldt åben tilstand, når dyrene betjener 35 ventilen, men man kan med et let fingertryk holde ventiltappen i denne stilling og evt. holde ventiltappen i 6 DK 169273 B1 denne stilling og evt. rokke den lidt for at rense ventilen, hvis denne observeres at være tilstoppet eller spærret mod at kunne lukkes.In the embodiment shown in FIG. 5, the recess 22 is located just off the valve passage 12. It can be seen that the length of the passage and therefore a substantially stronger flow can now be effected, whereby any deposited impurities can be flushed away. This position will normally only be occupied very briefly during the valve pin movement back and forth between fully closed and fully open state when the animals are operating the valve, but with the slightest finger pressure, the valve pin can be held in this position and possibly. hold the valve pin in 6 DK 169273 B1 this position and any. shake it slightly to clean the valve if it is observed to be clogged or blocked from being closed.

Det skal bemærkes, at ventilen ifølge opfindelsen 5 naturligvis ikke er begrænset til anvendelse i pelsdyrbure, da den i almindelighed er velegnet, hvor overskudsvand ønskes undgået.It should be noted that the valve according to the invention 5 is, of course, not limited to use in fur cages, since it is generally suitable where excess water is desired to be avoided.
